Key terms
Molarity
The number of moles of solute per liter of solution (mol/L).
Yield
The amount of product obtained from a reaction, often expressed as a percentage of the theoretical yield.
Molarity
Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.
Absolute uncertainty
Absolute uncertainty is the uncertainty of a measurement expressed as a fixed quantity, e.g., ±0.1 g.
Equilibrium Constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Boyle's Law
A gas law stating that the pressure of a given mass of gas is inversely proportional to its volume at constant temperature.
Independent Variable
The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.
Dependent Variable
The variable that is measured and affected in the experiment.
Molar Mass
The mass of one mole of a substance, typically expressed in grams per mole (g/mol).
Boyle's Law
A gas law stating that the pressure of a gas decreases as its volume increases, provided the temperature remains constant.
Molarity
A measure of concentration defined as the number of moles of solute per liter of solution.
pH
A logarithmic scale used to specify the acidity or basicity of an aqueous solution.
Equilibrium Constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium.
Activation Energy (Ea)
The minimum energy required for a chemical reaction to occur.
Equilibrium Constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Activation Energy
The minimum energy required for a chemical reaction to proceed.
Rate constant (k)
A proportionality constant in the rate equation that is specific to a given reaction at a specific temperature.
Equilibrium
The state in a reversible reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
Equilibrium Constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Partial Pressure (Kp)
The pressure exerted by a single component of a gas mixture, used in the context of equilibrium involving gases.
